Summary		(es) El plugin Laiser Tag para WordPress es vulnerable a la falsificación de petición en sitios cruzados en todas las versiones hasta la 1.2.5, inclusive. Esto se debe a la validación de nonce faltante o incorrecta en la función addOptionsPageFields. Esto hace posible que atacantes no autenticados actualicen la configuración del plugin, incluyendo la clave API, la lista negra de etiquetas, el umbral de relevancia, el tamaño de lote y los interruptores de etiquetado, mediante una petición falsificada, siempre que puedan engañar a un administrador del sitio para que realice una acción como hacer clic en un enlace.
